This paper presents a comprehensive review of dispersive Alfvén waves in space and
laboratory plasmas. We start with linear properties of Alfvén waves and show how the …

A review is given of several mechanisms causing outflow at high latitudes of ionospheric
ions to the terrestrial magnetosphere. The upward ion motion along the geomaagnetic field …

The FAST spacecraft observes Alfvénic fluctuations in field quantities throughout the auroral
oval. In this report, we show preliminary results from a statistical study of Alfvén waves with …

Observations obtained by the Freja satellite at altitudes around 1700 km in the high‐latitude
magnetosphere are used to study ion energization perpendicular to the geomagnetic field …

Recent observations have indicated that in addition to the classical “inverted‐V” type
electron acceleration, auroral electrons often have a field‐aligned distribution that is broad …

High‐resolution measurements by the Freja spacecraft of broadband extremely low
frequency (BB‐ELF) emission from dc up to the lower hybrid frequency (a few kHz) are …

Broadband electric field fluctuations with typical amplitudes of 10–20 mV/m peak‐to‐peak
and frequencies from 0 Hz to 3 kHz (BB‐ELF) were observed coincident with a region of≤ …

Recent auroral sounding rocket data illustrate the relative significance of two transverse
acceleration of ion (TAI) mechanisms for initiating nightside auroral ion outflow. First, the …

" Although Titan is similar in terms of mass and size to Jupiter's moons, Ganymede and
Callisto, it is the only one harboring a massive atmosphere. Moreover, unlike the Jovian …

We present initial statistical results of a new methodology for identifying electron
precipitation mechanisms in Earth's auroral zone. Unlike previous methodologies, it …
